How do you start Selenium+Firefox on Linux using a custom Geckodriver and Firefox path? (self.selenium)

from selenium import webdriver
from selenium.webdriver.firefox.service import Service
from selenium.webdriver.firefox.options import Options

options = Options()
options.binary_location = '/mnt/sdb1/firefox/'

driver = webdriver.Firefox(options = options, service=Service(executable_path = '/mnt/sdb1/root'))

driver.get('https://youtube.com')
driver.execute_script('alert(\'your favorite music is here\')')

I get the following error

Traceback (most recent call last):
  File "/mnt/sdb1/root/sele.py", line 8, in 
    driver = webdriver.Firefox(options = options, service=Service(executable_path = '/mnt/sdb1/root'))

    self.service.path = DriverFinder.get_path(self.service, options)

Honestly while you can use a local driver for selenium your much better off just using one of the docker images here and using a remote connection. If you insist on the local driver then your probably going to want to use a web driver manager to handle that for you so your systems browser doesn’t mess with it.

I need to scrape an internal website using the system browser via --marionette Eventually this will be turned into a windows script. I tried using webdriver-manager and got it working but I still need to specify a path to firefox and the site is internal. This is my script in Windows - it doesn't work. It uses GeckDriverManager but I'd prefer a hardcoded path.

from selenium import webdriver
from selenium.webdriver.firefox.service import Service
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from webdriver_manager.firefox import GeckoDriverManager

options = Options()
options.binary = FirefoxBinary(r'C:\Program Files\Mozilla Firefox\firefox.exe')

service = Service(GeckoDriverManager().install(), service_args = ['--marionette-port', '2828', '--connect-existing'] )
driver = webdriver.Firefox(options=options, service = service)
#pageSource = driver.page_source
#print(pageSource)

Use the full path to the executable and not just the folder it is in?

I think your options.binary_location needs to point directly to the executable. So: /mnt/sdb1/firefox/firefox

And executable_path should point to your geckodriver: /mnt/sdb1/firefox/geckodriver
